Title: Power converter generating electrical power from movement energy - involves spring-loaded component installed in roadway receiving forward and backward movement from passing vehicles
Inventor: REDZEPOVIC BAJRO
IPC: H02K7/18
Filed: 1991-12-23
Abstract: The converter consists of two main parts, viz. spring-loaded (1) and movement conversion (2) components. A third part generates the electrical energy. The spring-loaded component is located in a roadway to be pressed downwards by passing vehicles and to spring back again when the vehicle has passed. Such movements are converted into rotary movement which, in turn, activates the electrical generator. The spring-loaded component is a double ramp (6) extending over the complete width of the roadway so that it can be activated by traffic in both directions. The ramp has two plates (7,8) which, in the longitudinal direction of the road (4), are located closely to one another, their ends (7a,8a) being articulately connected to the road. The facing ends of the plates (7b,8b) are held over the roadway by springs (9,10). The arrangement of the plates is such that they adopt positions in which they are slightly inclined upwards towards each other. The inclination is scarcely noticeable since the plates are several metres long.
